PI2SSD3212
1.35V/ 1.5V/1.8V 14 bit 2:1 SSD Switch
This 14-bit SSD switch is designed for 1.35V/ 1.5V/ 1.8V supply
voltage, POD_12, SSTL_135, SSTL_15 or SSTL_18 signaling
and CMOS select input signals. It is designed for DDR2 or DDR3
memory bus with speed up to 5Gbps. It supports DDR3 1866
Mbps.
PI2SSD3212 has a 1:2 demux or 2:1 mux topology. All 14-bit
channels can be switched to one of the two ports simultaneously
with the SEL input. This device also allows all ports to be
disconnected.
PI2SSD3212 uses Pericom’s proprietary high speed switch
technology providing consistent high bandwidth across all
channels, with very little insertion loss, cross-talk, and bit to bit
skew.It is available in a 52-pin TQFN 3.5x9x0.4mm package and
48-pin TFBGA 4.5x4.5x0.8mm package.
